Linshang UV LED energy meter (radiometer) spectral response is 340-420nm, calibrated at 395nm UV LED light source. If we use it to test the 365nm light source, will the data be accurate?

1. How do you measure the energy of UV LED light?

Linshang Technology has invented two UV LED energy meters, LS128 and LS131. These two uv measurement devices are designed for measuring the energy of UV LED light. The spectral response range is 340-420nm. It can measure UV LED light sources of various wavelengths such as UV LED 365 nm, 375 nm, 385 nm, 395 nm and 405 nm. These two instrument UV LED radiometers are calibrated at a 395 nm UV LED source, which means that we use the 395nm light source to examine and calibrate the UV puck.

2. How do I know whether the UV energy is accurate or not?

Before we understand the accuracy of the data, we need to tell you that there is no uniform measurement standard for the UV intensity or UV energy measurement of UV LED light sources worldwide. Therefore, all major LED UV radiometer manufacturers use their own standards to calibrate the UV LED puck. In other words, if we want to determine whether the LED-specific UV radiometer data is accurate, we need to refer to the manufacturer's own standards.

3. What's the difference of the LED light source and high pressure mercury lamp spectral response curve?

The spectral response graph of the LED-specific UV energy meter is different from that of the high pressure mercury lamp. The spectral response is the same in the range of UV LED 365nm to 405nm. From the figure below, we can see that this graph is very in this stable in this range. Therefore, no matter what band of UV LED light source data is tested, it is no problem. Although we choose one wavelength to calibrate the instrument, it also ensures the accuracy of the data when measuring other wavelengths.

All in all, using the LS128 or LS131 UV LED energy meter to measure any LED light source in the 365-405nm range, the test data is in line with the manufacturer's standard of Linshang technology, regardless of the LED light source calibrated in what band. Please feel free to buy and use.
